Luka and his Stallion of the Cimarron

For all his life, Luka Couffaine lived in a Music Loving Tribe in the Great Plains, becoming the leader of his beloved tribe at the age of seventeen. When something new arrives one night, his life changes as Luka sets off on a journey that takes him and his loyal stallion across the plains, where he meets Gabriel a colonel of a cavalry, Adrien from another tribe and Marinette from Adrien's tribe. As much as he wants to return home to his tribe, Luka is shown by Marinette of how different yet magnificent the many worlds are in the Great Plains.
